12th International Symposium on District Heating and Cooling

The <strong>12th</strong> <strong>International</strong> <strong>Symposium</strong> on District Heating and Cooling,September 5 th to September 7 th , 2010, Tallinn, EstoniaCONCLUSIONThe main conclusions from the analysis were:Fig. 8 Average heat use in multi-family buildings inrelation to the measures performed. The measure figurescorrespond to the measures defined in the text.Individual variations dominate compared tosystematic causes regarding the specific heatuse in multi-family and service sector buildings.The district heating companies can help theircustomers by identifying them as high, mediumor low users of heat.On the short term, a significant potential existsfor lower heat use in the Swedish multi-familyand service sector buildings.More efficient heat use in buildings will probablyrepresent the most important competitor todistrict heating supply in the future.Fig. 9 Average heat use in service sector premises inrelation to the measures performed. The measure figurescorrespond to the measures defined in the text.As shown in the figures 8 and 9, there were nosubstantial differences in heat use between buildingswhere energy-saving measures had been taken andthose where they had not. The conclusion from thisanalysis is that the measures taken during these 10years were taken by late-comers rather than by earlyadopters, since heat use after measures were takengenerally corresponds to the average level for allbuildings.In the Swedish energy efficiency debate, manyvoices refer to systematic causes for high heatuse. However, the results from this study do notsupport this opinion, since the distribution ofheat use mostly comes from individual causes.The most important implication of the studyresults is then that systematic policy measureswill have a low impact on total national energyefficiency.REFERENCES[1] Statistics Sweden, Energistatistik förflerbostadshus 2006 (Energy statistics for multifamilyhouses during 2006).
